How to improve the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipe

Views: 0    

At present, there are many applications of reinforced 3pe anti-corrosion steel pipes. However, due to the low precision of the wall thickness of reinforced 3pe anti-corrosion steel pipes, there is a phenomenon of uneven thickness, which will have a great impact on the performance of reinforced 3pe anti-corrosion steel pipes. It affects the service life of the reinforced 3pe anti-corrosion steel pipe. Therefore, the manufacturer of the reinforced 3pe anti-corrosion steel pipe has taken some effective measures to improve the wall thickness accuracy of the reinforced 3pe anti-corrosion steel pipe.


How to improve the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipe?

1. For the heating of the tube blank, we must pay attention to the uniform heating, prohibit the rapid rise and fall of the temperature, and keep the rise and fall of the temperature stable.

2. Use the centering roller to determine whether it is in place, and adjust the center axis and opening angle of the core roller.

3. The rolling tools should be installed on the rolling line to ensure that the upper and lower roll distances are equal, and the left and right lead distances are equal.

Fourth, the rolling mandrel chooses the pipe with a larger wall thickness for processing, and the pipe with uniform wall thickness can reduce the probability of deformation of the mandrel and improve the wall thickness accuracy of the steel pipe.

5. Improve the process, which can also improve the wall thickness accuracy and avoid the situation where the middle is thinned and the wall thickness exceeds the control range.
